FindVulkan
----------

Try to find Vulkan

IMPORTED Targets
^^^^^^^^^^^^^^^^

This module defines :prop_tgt:`IMPORTED` target ``Vulkan::Vulkan``, if
Vulkan has been found.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables::

  Vulkan_FOUND          - True if Vulkan was found
  Vulkan_INCLUDE_DIRS   - include directories for Vulkan
  Vulkan_LIBRARIES      - link against this library to use Vulkan

The module will also define two cache variables::

  Vulkan_INCLUDE_DIR    - the Vulkan include directory
  Vulkan_LIBRARY        - the path to the Vulkan library
